Password Reset for Users on a Multisite Subsite

Question

I have a multisite network. I want my users to be able to reset their passwords while staying within their subsites. So for example clicking the "lost your password?" link keeps them within their subdomain (subdomain.domain.com/wp-login.php?action=lostpassword) as opposed to taking them to the main site (domain.com/wp-login.php?action=lostpassword).

After they submit the username or email to reset the password, I would like for that email to contain links back to their subdomain and not the main site as is the default functionality.

Prior to the 4.0 update I was able to use this patch https://core.trac.wordpress.org/ticket/21352 and ultimately this plugin https://gist.github.com/strangerstudios/9487278 to get the exact functionality described above. All was great.

However after the update it is no longer working. Asking for assistance in the various places referenced has still not helped solve the problem. Is anyone able to help?

This works well!
